BR3100 - 100Amp Circuit Breaker Description
BR3100 - 100Amp Circuit Breaker
The Eaton BR3100 is a 100 Amp, 3-pole thermal magnetic circuit breaker designed for use in compatible Eaton Type BR loadcenters. It's commonly installed on higher-capacity circuits serving equipment that requires more power than a typical branch circuit, making it a familiar breaker in commercial buildings, workshops, mechanical systems, and light industrial facilities.
Rated for 120/240V applications with a 10 kAIC interrupting capacity, the BR3100 accepts #1 AWG copper or aluminum conductors and is built for circuits requiring a 100 Amp three-pole breaker. You'll often find it used with HVAC equipment, motor-driven machinery, distribution circuits, larger mechanical loads, and other applications where additional capacity is needed. For electricians working in Eaton BR panels, matching the correct breaker series is just as important as matching the amperage rating, and that's where the BR3100 fits into the system.
